Kit composition

This kit supplies 64GB of DDR4 laptop memory arranged as eight 8GB modules. It targets owners of compatible laptops, all-in-one PCs or NAS units that accept 260-pin SO-DIMMs and need a single-package upgrade to the maximum capacity their platforms allow.

Interface limits

The modules run at the JEDEC-standard DDR4 3200MHz PC4-25600 data rate with CL22 latency at 1.2V. Systems that only support lower DDR4 speeds will down-clock the kit automatically, and platforms restricted to fewer than eight SO-DIMM slots cannot use all modules.

Capacity ceiling

Eight slots filled with 8GB sticks deliver 64GB total, enabling heavy multitasking, large-file editing and virtual-machine workloads. Machines limited to four slots or a 32GB firmware ceiling will leave half the kit unused, so buyers should verify their device's slot count and maximum supported capacity before purchasing.

Questions about this item

Should I pick the 64GB kit with eight 8GB modules or a different capacity?

This kit provides 64GB total across eight 8GB modules, giving you the full capacity in one matched set.

What does the 3200MHz speed mean once the RAM is installed in my laptop?

The modules run at 3200MHz with CL22 latency at 1.2V, and the system will operate them at the highest speed the memory controller supports.

What does the 260-pin DDR4 SO-DIMM interface cap in practice?

The 260-pin DDR4 SO-DIMM form factor fits laptop slots wired for DDR4; maximum speed and voltage are set by the platform's memory controller.
